from Four Quartets - Burnt Norton - T.S.Eliot 

Go, said the bird, for the leaves were full of children,
Hidden excitedly, containing laughter.
Go, go, go, said the bird: human kind
Cannot bear very much reality.
Time past and time future
What might have been and what has been
Point to one end, which is always present.


Extra - Holkham beach taken today but with echoes of time past
